Laser diode array side pumped medium aperture Nd:glass square rod amplifier

A laser diode array side-pumped Nd:glass square rod amplifier of the dimensions 12 mm×12 mm is designed. The fluorescence is evenly distributed in the Nd:glass amplifier. When the pump power is 66.32 kW, the small signal gain increases by 3.23 times. Under the condition of a 1 Hz repetition frequenc
